Warner Bros. Interactive Entertainment offers a terse announcement that the Windows edition of Batman: Arkham City will miss the planned October release dates for the superhero sequel, though the console editions are still on track for release in North America on October 18th, in Australia on October 19th, and in Europe and other territories on October 21st. Here are some new screenshots, and here's the announcement:

Warner Bros. Interactive Entertainment and Rocksteady Studios are releasing the PC version of Batman: Arkham City in November. The Xbox 360 and PS3 versions of the game will be available on 21st October in the UK.

On a semi-related note, Joystiq notes that GameStop has word that the Batman: The Animated Series skin is a PowerUp Rewards member exclusive (thanks nin via Shacknews), though it was recently revealed that the preorder skins will also be offered as post-release DLC.

I don't think you are following me Creston. They have competition whenever they release it. Doesn't matter what that competition is. The PS3 & 360 versions are still out October. PC version is delayed a few weeks. With about 10 big games and dozens of others is an eight week period...it simply doesn't matter if it hit PC Oct 18 or Nov 18. And yes BF3 is out late Oct, forget exact date.
